Are Pashtuns descended from the lost tribes of Israel?

Genome-wide studies do not support it. Pashtun genomes fit the local mixture of Iranian farmer-related, AASI and Steppe ancestry seen across northwestern South Asia. The Y-chromosome lineages sometimes cited, branches of J and E, are common across all of West and South Asia and do not point to a Levantine source. The tradition is part of Pashtun culture, not a finding of population genetics.

How much Steppe ancestry do Pashtuns have?

Among the highest in South Asia. Published models put the Steppe MLBA share for Pashtun and neighbouring Hindu Kush groups at roughly a quarter to a third, with the exact figure depending on the proxies used. The paternal side is more Steppe-shifted still: around half of Pashtun men carry R1a, the lineage the Steppe pastoralists brought.

Which ancient genomes are closest to Pashtuns?

The Iron Age and historical-period people of the Swat valley in northern Pakistan: Loebanr, Katelai, Aligrama, Udegram, Butkara and Saidu Sharif, dated from about 1200 BC to the first millennium AD. They carry the same three streams in similar proportions. Farther back, the Indus Periphery individuals represent the pre-Steppe base.

Do Pashtuns have Greek ancestry from Alexander's army?

No study has found a Greek-specific signal in Pashtun genomes. Greek settlement in Bactria and Gandhara is historical fact, but the population those settlers joined was already Iranian- and Steppe-related, so any small Balkan contribution would be hard to separate, and none has been detected.

Are Pashtuns genetically Iranian or South Asian?

Both descriptions are partly right and neither is complete. The largest stream is Iranian farmer-related, but it arrived in the Indus region thousands of years before Iranian-speaking peoples existed, and Pashtuns also carry AASI ancestry that plateau Iranians lack. On a cline they fall between the Iranian plateau and the rest of South Asia, closest to other Hindu Kush groups.
