Yes many types depending on application and lead free alloys as solder by definition means lead. Solder such as 40 - 60 50 -50 60- 40
Lead is toxic to humans (causes brain damage) thus when using a solder to join copper water pipes it is best not to use a solder containing lead as this will get into the water passing through the pipes and slowly poison the user of this water.
"Solder" can be a noun or a verb. The following sentences provide examples of both:You should use lead-free solder for work on kitchen plumbing fixtures.I got Ben to show me how to solder the electronic components in the kit.
Lead-free solder began to be widely used in the electronics industry in the early 2000s, following regulations such as the European Union's Restriction of Hazardous Substances (RoHS) directive which restricted the use of lead in electronic devices.
The compound symbol for solder can vary depending on the specific composition. Common solder compounds include tin-lead solder (Sn-Pb) and lead-free solder such as tin-silver-copper (Sn-Ag-Cu) or tin-copper (Sn-Cu).
Use lead-free solder, 0.2 percent lead or less. Lead free means NO Lead your better off with a silver bearing alloy as it has a longer pasty range or 95% tin 5% antimoney Actually the term "solder" means lead bearing according to the AWS specifications

Most commonly, but antimony is another basic component of some solders. The European Union, China, and California are areas where lead solder is banned in consumer products. Tin-lead solders were most often used because they are easily melted and inexpensive. Lead-based solders have a few problems which are reducing their popularity: - Environmental concerns about e-waste - Worker safety concerns for people who constantly work with solder - The low melting point, which is not suitable for modern microprocessors Any metal which is melted to bond to another metal is a solder. Silver solder is used to repair silver jewelry, and gold solder to repair gold. Silver solder is also used in food-grade plumbing. Drinking water is soldered with lead-free solder (but lead was used in nearly all plumbing soldering until the late 1980s).

Since question is not clear two answers can be given on the assumption that the question is about dry soldering. Thoroughly clean the part to be soldered, apply flux re-solder the connection. The second answer is normally lead will not be kept on a soldering point. the technician doing soldering has to use lead and flux separately. ================================ There are still solders that contain lead. The European Union prohibited excessive amounts of lead in consumer products (WEEE and RoHS), so there are lead-free solders. But there are industries in which the lead-free solders are not acceptable.
