Yeah i am also excited to release this thing to see people playing with those Ultimates, they offer an
Audio Adrenaline when you are in a
Pressure Zone resulting in a
Collapse of monsters so they don't
Fuck U Up! when trying to get you
Swallowed 
1. They are avaliable when you get 30 frags precisely, that white Icon above all weapon icons in the HUD is what tells you when it is ready.
2. Yes, the PG Ultimate will track who you are aiming until it is dead then it will proceed to nearby targets, it lasts 15 seconds and will bounce off walls and floors when it have no target, though this will not work for bosses since the ball works with piercing the monsters which are not the case of those.
3. Kinda, both of them are 384 radius explosions, though the damage amount is different between them, grenade explosion is lower than RL since it scatter regular grenades in all directions.
4. HELL YEAH YOU CAN! Also each monster hit by Railgun's ultimate will cause a small explosion on it, nearby monsters killed by it will also give impressive medals (so yeah using it in a clusterfuck of monsters will gives you Impressive medals FTL)
5. They are basic weapons as Gauntlet, i decided to not give them an Ultimate as well the Special weapons because there's Chaingun already and all other guns have their primary damage pretty high too.
6. The bell ring means you picked up a
Kamikaze, though item is useless in single-player because requires your death to work properly as it does in Quake 3 Team Arena, every time the medals counter resets it means you got one of those, 50 Excellent medals gives one kamikaze, 30 Impressive medals gives one Orbital Strike (OEDB), actually i'm also thinking in change this to make the medal manager gives the player a different item when earning the 50 Excellent medals in SP, so this don't becomes so useless.
P.S: One fun thing that i have to say, that spell ring my NPC does when creating the Black Hole actually have readable words on it, i just picked a font that makes it looks like ancient writing but still is written in english.
