Yes, you can store it at -20 C without any problem. In some protocols it is reccomended to not store for more than one month, but actually it can be stored for several months. For longer periods (years) I would prefer to purify, suspend in TE and store at -20 or even better at -80C.

One of my colleagues was hurry at weekend, forgetting he put it in his hand bag instead of putting in freezer and next week he found it OK. I put it at 4 C for more than a month and found OK. -20 C is nice for several months but put it in deeper in the freezer if you want to forget it for several years.
Like you can store purified DNA at 4degress or -20degrees for months, the same way you can store PCR prodcut also. Sequencing won't be affected by that as DNA is very stable.
PCR products are incredibly stable - even more so than genomic DNA. I've had products that were stored at room temp in a bench drawer for several years which I was able to both direct sequence and TA-clone with no problems. The only thing to maybe avoid is multiple freeze-thaw cycles (which can cause shearing), so if you're going to be using it a lot in a relatively short time period it's probably better to go with 4oC refrigeration instead of freezing. Although even there it's more a problem with genomic DNA than PCR products.
Accidentaly I leave pcr products during three days at room temperature (19°C) and it was sequenced after without any problem, PCR products are very stable
Yes you can store for long time as much as you can @ -20 to -50 degree, during this also avoid freezing and thawing cycles, this might influence your product.
Yes, absolutely. PCR products can be kept in -20 for years. Avoid freeze thaw cycles. I recently got a sample sequenced that was kept in -20 for over a period of 13 months. The sequencing results established that there was no degradation.
