Opinion on fixing 6 older violins?

[Tiennou74]

A neighbor is selling a few violins for under 200$ each - are these worth repairing or the cost would outweigh the value?
Are they what they are said to be?

1. Violin 1 Janurius Galianus 1712 - top plate crack

 

2. Leandro Bisiachi, Milano 1922. - Looks like soundpost crack on back plate + top crack near neck

3. Villaume a Paris

4. Cremonena? Weird varnish and painted fingerboard?

5. John Juzek 1930, Make in Prague, Portland institute of music.

6. Jackson Guldon

1. Bass bar crack - not worth

2. top and back SP cracks? Not

3. pegbox seems to be cracked in few places plus few badly repaired cracks - Not

4. Cheap fiddle possibly refinished, not

5. seems to have no structural damage, may be worth buying

6. Very cheap school fiddle. not

Well, you could use the Jackson-Guldan to start the fire.
