How many almonds a day can cause toxicity for vitE?
You can eat bags and bags of almonds every day for years and not be in any risk of vitamin E toxicity. There are many, many cases of adults consuming 500+ mg of Vitamin E every day, for years on end, with no signs of harm.

In general though, the max daily recommended value of vitamin E consumption is 1000mg. One cup of almonds (100g, or ~100 kernels) contains a little under 30mg of vitamin E. That being said, you can consume over 30 cups of almonds in one day before reaching the daily recommended limit. 

You would have to eat tens of hundreds of thousands of almonds for there to be any kind of health concern.. at which point, you would probably suffer from other conditions than vitamin E toxicity. 

You (should) have nothing to worry about.
