Wands need verbal components and to do that you need to speak underwater which requires you to be able to breathe underwater. If it's very specific like guns, then it needs an air bubble or special enchantment. If you're a wizard under the water I hope you have freedom of Movement + water breathing and the ability to speak underwater otherwise you won't be able to as I found out on my Druid who turned into a squid but forgot Beast Speak.

I'm not 100% sure on metamagic spell wands, but if they are allowed I'd imagine they'd follow the same formula
So the spell couldn't be above 4th level after the metamagic level adjustment, and you'd have to pay the crafting price accordingly based on the new level, and potentially caster level as well as some metamagic require a minimum caster level to learn.

I'm pretty sure intense spells only applies to spells you actually cast. It doesn't apply to spells cast from or a wand or spells used to create magic items.

Your first question has been answered.
Your second question, the answer is yes, you can make a Wand of Intensified Fireball for example. But the Wand must be made with Intensified Fireball and this is a 4th level spell with a minimum caster level of 7 (why would you do that - better make it at least 11th level, preferably 15th level, to benefit from the metamagic).
Of course, this changes the price of the wand. And, it means you could give the wand to any arcane caster and they can cast the Intensified Fireball even if they don't have Intensified Spell as a feat.

1. Certainly; Harry potter did it. Seriously speaking though, grappled and underwater doesn't matter as long as the wand is in his hand.
Spell trigger activation is similar to spell completion, but it's even simpler. No gestures or spell finishing is needed, just a special knowledge of spellcasting that an appropriate character would know, and a single word that must be spoken.
2. If you mean any user benefiting from intense spells if they used that specific wand, certainly not. I would also recommend you don't if you're asking for people's advice.
If you mean by only the wizard casting from *any* wand, that seems reasonable. I don't know by RAW if it's allowed, but I would kinda think so? Using a wand is still the caster casting a spell isn't it?
Either way I think it would be reasonable to allow.
I would think it would be best to use the wand's caster level for calculating the bonus damage in such case though rather than the caster's level.

Specifically, no the caster isn't casting the spell, it's coming from the wand. It doesn't use the caster's level, or casting stat, or any special bonus the caster has. Even a staff has limits, and that uses both level and casting stat.

You can cast spells with verbal components underwater, so a wand with a command word should be no more difficult than that (and probably easier).
(I wonder if this might also apply to other magic items with verbal activation?)
Spellcasting Underwater: Casting spells while submerged can be difficult for those who cannot breathe underwater. A creature that cannot breathe water must make a concentration check (DC 15 + spell level) to cast a spell underwater (this is in addition to the caster level check to successfully cast a fire spell underwater). Creatures that can breathe water are unaffected and can cast spells normally. Some spells might function differently underwater, subject to GM discretion.
