Summary: The primary purpose of this study is to determine: the recommended Phase 2 doses (RP2Ds) of JNJ-64264681 and JNJ 67856633 when administered together in participants with B cell non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) (Part A - Dose Escalation); and the safety of the RP2Ds for this combination in different histologies/participant populations (Part B - Cohort Expansion).

Inclusion Criteria:

- Eastern Cooperative Oncology Group (ECOG) performance status grade of 0 or 1

- Cardiac parameters within the following range: corrected QT interval (QTcF) <= 480 milliseconds

- Participants with B cell non-Hodgkin lymphoma (NHL) must have tumor tissue available at baseline as described in the protocol. This is not required for participants with chronic lymphocytic leukemia (CLL)

- Women of childbearing potential must agree to use a barrier method of contraception; use a highly effective preferably user-independent method of contraception; not to donate eggs (ova, oocytes) or freeze them for future use for the purposes of assisted reproduction during the study; not to plan to become pregnant; and not to breast-feed

Exclusion Criteria:

- Part A and select cohorts in Part B: Prior treatment with JNJ 64264681 or JNJ-67856633. Previously discontinued treatment with a Bruton's tyrosine kinase (BTK) or mucosa-associated lymphoid tissue lymphoma translocation protein (MALT) inhibitor other than JNJ 64264681 or JNJ-67856633 due to participant or doctor choice without evidence of progression or intolerable class-related toxicity will be eligible

- Known (active) central nervous system (CNS) involvement

- Received prior solid organ transplantation

- Participant has known allergies, hypersensitivity, or intolerance to JNJ-64264681 or JNJ 67856633 or excipients

- Toxicities from previous anti-cancer therapies that have not resolved to baseline levels, or to Grade less than (<) 2 (except for alopecia [>=Grade 2], vitiligo [Grade 2] and peripheral neuropathy [Grade 1])
