Spokesman Randeep Singh Surjewala also met Rahul Gandhi at the latter's residence. Gehlot arrived after Pilot had left.
Details of their discussions were not immediately known.
Gandhi had offered to quit as the party President at the Congress Working Committee (CWC) meeting on Saturday but it was unanimously rejected.
The CWC, the party's top decision making body, authorised Rahul Gandhi to make structural changes in the country's oldest political party.
But party sources maintained that Rahul Gandhi was firm on quitting, triggering concern in the party that has always worked under the Nehru-Gandhi umbrella.
Priyanka Gandhi first arrived at Rahul Gandhi's residence in the morning followed by Surjewala and Venugopal. Pilot reached the residence some time later.
After separate meetings with Rahul Gandhi which lasted for over 50 minutes, Pilot, Venugopal and Surjewala left.
Gehlot then reached the Gandhi residence.
On Monday, Gandhi had declined to meet Gehlot despite an appointment and asked him to meet Venugopal instead.
Congress Uttar Pradesh leader Pramod Tiwari also met Rahul Gandhi.
The Congress is expected to call another CWC meeting within the next four days.
Rahul Gandhi had blamed Gehlot and Madhya Pradesh Chief Minister Kamal Nath for devoting more time in the constituencies of their sons instead of doing more for the party in the elections in which the Congress won just 52 Lok Sabha seats.
