205/60-15 or 175/70-15
Yes, that is a good swap.
NO. Rim size incorrect, they will not fit.

185 /65/15
Yes, this is an excellent substitute.
They will of course fit but there is a problem with going to a larger diameter tire. Your speedometer will be off. A much better replacement would be a 195/60-15 which is almost the exact same diameter.
No, your speedometer will be off and power and fuel mileage will be adversely effected.
You can replace them with 205/60-14 or 175/70-14.
Yes as long as you keep the overall diameter the same. For instance you would replace a 185/75-15 tire with a 215/65-15 tire which would keep your overall diameter almost the same. Click the link to calculate what size tire to go with.
