How do I fix the handle of my huffy blackwater women's bike so that it synchronizes with the wheel?

You can't bend it back you need a new one.

If the thread on the crank arms that hold the pedals are stripped, you will need a new set of cranks. That is definitely a job for the bike shop. Make sure the pedals are snug in the arm, Right side pedal has right-hand thread, left side (looking down when you are on the bike) has a left-hand (reverse!) thread.

Take it to a Bike Shop to get the cables and housing. This isn't novice work.

You can use the 6 speed rear derailleur with no problems. The 5-spd shifter does not need to be disabled, as it will work just fine.

The shifter controls the rear derailleur, telling it how far to move. The rear derailluer just follows what is dictated, so there is no real difference mechanically between the 5spd and 6spd derailleurs, only in the shifter.

If you wanted to make the bike 6spd, you would have to change the shifter and gears along with the derailleur.

If you remove the wheel can you spin the gear cluster forward with no resistance? Does it ratchet when spun backward? If yes and no, the hub is shot.

The pedal should not be able to reach the front tire. Sometimes one gets their toes to overlap the front wheel on a racing bike but that's because they have intentionally short wheel base and a steep for angle. Which way is the fork on your bike pointing? It should be angled or curved forward.

Look at the bike icon on this posting for an example.

Go to parktool.com/repair for information on bike assembly, disassembly, repair and tuning. The assembly of any bike is more or less the exact same as any other, so this website will give adequate instruction for your bike.

If you can see where it gets caught up at then you can take it to your nearest dealer or shop where they can fix it.
It is probably a simple bend in a sprocket or warp of some type, even may be a manufacturer defect!
