Ball stuck in glove

[Larry1953]

Nobody on, nobody out. OBR. Batter hits a hard one hopper back to the mound. F1 catches it in his glove but the force of impact causes the ball to get stuck between the middle and ring finger slot in the glove, knocking the glove off the pitcher's hand. F1 takes a beat or two to recover and realizes it will be close at first especially since he can't dislodge the ball. He underhand frisbee flips the combo to 1B. The throw is wide into the baseline which causes F3 to have to come off the bag, stretching with his throwing hand to snare the frisbee. F3 just has time to tag the B/R running by with the ball/glove combo in his throwing hand.

Question 1: as this a legal tag?

Say F3 is able to keep his foot on the bag:

Question 2: is it sufficient possession for the "force out" if F3 "claps" to catch it between throwing hand and glove?

Question 3: is it sufficient possession if F3 cradle catches the combo against his chest like a football.

Question 4: is a fielder permitted to make a play on a batted or thrown ball or on a runner while his is in possession of more than one glove?
