I wanted to ask if I uploaded a image which was a jpg and the artist release again on pixiv.net png is the old one deleted?

I think it's situational.
Usually I think you would opt for whichever one has the higher resolution because those are usually the higher-quality version but sometimes there are revisions that are inferior to the original (see has_bad_revision) and should be avoided.

If you post both simultaneously or someone else posts a higher quality image while yours is in the queue (1up), the one with lower quality may end up being deleted.

Question if a image was jpg around 1500 x 2200 and I uploaded a png 845 x 1500 would it get rejected as a low quality?
Depends how approvers feel about it. Generally speaking the highest resolution least lossy image is approved, so if the JPG isn't bad or has other merits the PNG might be rejected. I'm not an approver but I've run into this exact situation before, because yukie (kusaka shi) does this all the time, uploading higher res lower quality images on Twitter and the same image lower res higher quality on Pixiv.
Basically, it's a gamble. Upload the least lossy file format as a priority. Don't upload duplicates without a good reason, leave that to the purples trying for a high score on Danbooru.

Not everyone here is here for fake internet points (admittedly some are), many people here are just here for their love for the artworks and archiving them.
You're correct that generally it's tougher for lower-resolution duplicates to get approved even though the quality is better in other aspects (e.g. JPG vs PNG), and it's probably inadvisable to upload those without being unrestricted. The reason you see them uploaded however is that many people (including myself) deem it worthwhile to also save lower resolution but higher quality (sometimes even lossless) images.
They got banned but anyway, the image they were reffering to looks like a minor revision, so I approved it. Personally, I'd skip a .png with less resolution than the parent if it was identical and had other defects, I wouldn't post an image like that either.
