Tough live 1/2 hands- first post

Live 1/2 home game.

Villain is the same in all three hands. This was only the 2nd hand of the night and I had no reads. $200 stacks
1 fold, Hero raises $7 with AA, MP1 calls, rest fold
FLOP A,Q,4 rainbow.
Hero bets $13, MP1 raises to $50, Hero?????
What is the best plan to extract the most value here?

By now I know villain is extremely loose and has built his stack up to around $500-600 with a couple wicked beats. One hand on a QJx board he shoved allin into a guy with $200 and showed Q8 after a fold. I have a $200 stack.

6 folds, MP3 calls $2, Villain (Button) raises to $15 (claims to be raising blind), 1 fold, Hero is BB with KQos. What is our play here? Do you reraise OOP? What is the plan on a Q or K high flop? MP3 is a bad weak tighty and is folding around 80% of the time.

Skip ahead 4 hours, same Villain as before has around $700 now making humongous $200 raises in $20 pots and winning.

2 folds, Hero raises to $7 with AJos, folds to BB who calls.

FLOP A,Q,J rainbow
BB Checks, Hero bets $13, BB calls and claims "I have a pair but I think I can suck out."
Turn 5
Villain announces allin for the $200 I have left. Are we ever folding this?
Villain is known for calling with crap from any position like 94s, 105s etc.

Please tell me if there is a better way to post live hands. Thanks.

AA - I call and check raise AI on turn.
KQ - I fold as I dont like raising and you can't be sure what the 3rd player is going to do.
AJ - I'm not getting away from this.

Hand 1. Agree
Hand 2. Fold. Playing KQo OOP profitably isn't the easiest thing to do
Hand 3. Any read on him postflop? TPTK is often good against a maniac, let alone 2 pairs.

Hand 1: definitely call flop, and check bomb him on the turn
Hand 2: Against some villains I might re-pop this preflop. But this villain seems to be a pain, and I don't wanna be OOP against an aggro opponent, so I prob fold this PF.
Hand 3: no getting away from this. I call, and I river an A or J if he shows K10 =)

Hand 1 AA

FLOP: AQ4
Hero bets $13, MP1 raises to $50, Hero calls $50.
TURN: 5 (Pot $117)
Hero Checks, Villain Checks
River: 9
Hero bets???

Hand 2 KQos
6 folds, MP3 calls $2, Villain (Button) raises to $15 (claims to be raising blind, rest of table confirms), 1 fold, Hero calls from BB KQos, MP3 Folds
FLOP: Q104 Rainbow (Pot 33)
Hero Bets $26, Villain (looks at cards) and raises to $200, Hero?!?!
