Can I vape at .35 ohms on a vct5 and how low can I go we'll staying safe on this battery
Are these ohms safe

It's reasonably safe , you'll be pulling 12 amps on a fresh battery but what do you need to go lower for ? You should have this already if you're doing .35 builds . Ohm's Law Calculator
Be sure to monitor the resistance of your coil once in awhile and the level of your battery.
Don't allow your batteries to drop below 3.6 volts before charging them.

Two other factors to consider is wire gauge and air flow. If the wire is too thin (30g +) or not enough air flow you can burn your juice and wick. But as far as battery safety goes you are in the safe zone. I'm not sure what device your using but some mechanical buttons are not rated for that current draw (like the old REOs before the upgraded contacts)

VTC5's are rated at 30A continuous.
Giving yourself 20% headroom for safety, you're safe below 24A or above a 0.175 ohm coil. .175 ohm is the lowest you'd want to go.

IF your batteries aren't fake VTC's and IF your ohm meter is accurate, should be, but if you bump the coil or a screw comes loose...
I wouldn't go any lower until you can verify the if's.
the below calculations from an Ohm's law calculator demonstrate that the lower you go in ohms the higher the amp requirement becomes.
You are also putting a lot of faith into a cheap ohm reader in being precisely accurate to the tenth/hundreth of an ohm. These readers can be off as much as +/- 0.15 ohms if not more. A loose post screw can cause a change in resistance unknowingly. Always tend to err on the side of safety when you make your builds by allowing some safety head room.
1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway
